I used to collect many things
first thing I can recollect collecting (good pun) 
were butterflies....
I used to catch them during vacations and pin them to
styrofoam...then I went to school 
stamps (quite decent collection matter of fact), pins , cards,
few kilos of marbles
CD's....ties (only made in land of cravat)
Then again I realized that lot of things will not bring me happiness
au contraire in word of one and only Delboy Trotter
What I in fact collect are good times with friend & family
